I was curious if there was even a market for a custom built filter module using the 2069 and perhaps an SSM2056 ADSR eg to give it smooth EG's.The module I was envisioning would breakout the ADSR controls to knobs on the module to tweak.More knobs for the VCF controls.Add in a simple LFO with several waveforms to select.. controls for speed/depth and waveform select.

And let's throw in a MIDI interface to allow CV control of Filter Cutoff/Resonance and maybe LFO Speed/Depth. I'd limit it to just 4 digitally controlled potentiometers. But it'd also have up to 8 logic controls too for 0/5v outs to use on triggers/gates.

Any thoughts?Think there's a market for a few custom units?I can only guess they would have to sell for at least $250 each to cover parts/labor.. which would really be mostly ate up for parts and hardly anything left to cover labor
